Abstract:
A 200kW pilot scale DFB(dual fluidized bed) gasification system and FT(Fischer-Tropsch) system were investigated for BTL(Biomass to Liquid) process. The DFB gasifier is able to produce a high quality syngas for FT system since it inherently prevents mixing between product gas and combustion gas. In order to meet syngas purification requirement for FT system, high purity syngas cleaning technologies are necessary. In this study, tar, dust and parts of acid gases were removed in a wet scrubbing system and remaining acid gases and contaminants were cleaned by using a chilled-methanol (MeOH) absorption method at a high pressure condition. Syngas from the atmospheric gasifier was compressed more than 20bar and supplied for MeOH absorption tower which is able to remove COS and H2S under ppm level and also a respectable amount of CO2 in syngas. For FT system, iron-based catalyst was used in a fixed bed reactor. The reliability of the integrated BTL system was identified from long-term operation of 500 hours over several runs, and stable operating conditions were achieved. BTL diesel from FT reaction was compared with a commercial diesel fuel.
